So I blogged about my camping issue and I think I MIGHT have a solution. Prize camping!
I've put two prize camping chairs in my store. Camp for 100 minutes and get one of three pairs of shoes. You pick the pair you wanna camp for. There are two chairs so you and a friend can sit around and sort inventory and chat and get shoes at the same time!
They are in the back corner near the windows, near my $1L items
